This is a pack of four Trueblood T-Rex 450SE V2 Red Head Dampers. This upgrade replaces the stock o-rings...pack of four (set of two complete sets). The advantages of these dampers is simple. They are able to produce a more responsive and tighter head dampening response by filling the entire dampening area of the head block with material. The dampers are designed specifically for the T-Rex 450XL/SE V2 head block and spindle, giving a tight dampening solution without needing to over-compress the rubber with spacers. Also, because of their shape and material, the Pro T-Rex Head Dampeners are able to last much longer. These will not fit the V1 SE/S/SA/XL/X.

Should your product come with any molding flash:

1. Poke a small hole in the flash with an X-Acto blade.
2. Push the spindle through the damper stretching the flash onto the spindle.
3. Take the X-Acto blade and cut around the spindle next to the damper.
